I don't know the answer to your question, but I would think Windows Genuine Advantage would be able to figure this out (i.e., if you run two computers simultaneously and they both call in to Microsoft regularly, it seems easy enough to assume you've got it on two computers). I don't know whether they do this or not, but the capability seems likely.
